. To all whomc't may concern x Y v Be it known that. I, GUST-Ayn HOLTER, subject of the. King. ofNorway gresiding at Seattle, in the county of King'and :State of l/Vashington, have invented certain new and useful Improvement inrHydrauliolVIQ- following is i a 'sp ifitors, of which the cation. l l 1 a invention relates to improvements hydraulic motors and more particularly it relates to "that class of hydraulic motors which embody hollowcylinders wherein are disposed pistons that are adapted byisuit-v able mechanism to be moved reciprocally by the force of flowing water to, actuate an as.-

;sociated centrally. fulcrun edalever to cause a such lever to, oscillate to communicate power to dittierent mechanical devices Wlth -Wl110li such lever may be connected, and the object proximately midway between their two, ends of my improvement is to provide, a ehydrau-s :lio motor which shall be simple linitsflplay s by devices illustrated in of construction, durable and efficient in its operation and which shallube adapteld'when submerged in a. fixed. position within the swift current of a river or streampf water so that its actuating parts mayabe subjectedito the impact of such current; or when such actuating :parts are subjected to, the action of water supplied ,bypip'es from a higher elevation. I accomplish, this object the accompanying drawings whereine a Figure l is a plan vieyv of tone form of a hydraulic motor embodying invention,

rlexceptfthateach of such pistons is provided near its bottomend with three valve stops 55, 56 and 57, respectively, there being pivotally mounted in-the lower end of the piston 53 two" semicircular valve disks -58 and 59, and in the piston 54 two'similarlyformed semicircular valve disks, 60,"6l,'such valve disks being provided with bifurcatedr'lugs 62, :63, 64 and 65, respectively,*with which are pivotally connected the lowermostends I orlinks 66, 67,- 68 and 69, the links 7 and 'and- 68 by the same pivots 70 and 71 by whlch such links 67rand 68 are secured-to the v end of a fulcrumed cross-bar 72 thatis' 68 being identical with the links 39 and and being provided with similar engaging lugs 7 5, 7 6, 77 and 78,- and the links 66 and 69 being pivotally secured to the links 67 similarto the cross-bar 41, other'parts of the device shown inFig. 3 being-identical with similarparts shown in Fig-- IWhereifltlley are indicated bysimilar reference numerals. V

-The operation of my device, as illustrated in Fig. 1 may be described 'as follows: Thc k bottom ends of the cylinders 7 and 8 may be] connected with pipes 7 3 and 74 through which water under pressure is caused to flow with a suitable link bywhich such valvepart in the direction, shown bythe arrows, an'd'if the devlcebe in the position shown, such flowing water will exert force against the valve 19 and will move against the piston 12 upwardly within the c'ylinder'l, the piston 13" atthe'same'time moving downwardly in the cyl nder 8 with its valve 20"open, as" shown in Fig. 1.- As the pistonl2' moves upwardly it lifts the end of'the beam 24 and also lifts the opening-and closing link 39togetherwith the end of the'beam 41. The link 43 moves upwardly with the end 1 arm45 moves downwardly asthe arm 24 is raised, until the outer end of such lever arm 45 engages with the pin'50 in the link '39 and causes such link to open the valve 19 while at theisame time the lever arm 46, which-has "been moving in a direction opposite to the direction of movement of the link 45, en-

gages with the pin 51 to close the 'valve 20,

the valve 19 opening at the end of its Workng stroke at the same instant that the valve 20 closes at the end of its idle stroke and the water that is flowing through the pipe 74 and the cylinderS engaging with the valve 20 to move the piston 13 upwardlythus reversing the- {direction of movement of the *variouslinks and levers connected therewith.

The pistons l2and 18 thus continue their reciprocal motions within the cylinders 7 f and '8, the valves'19 and20'each closingiat the bottom of. its stroke and opening at the 7 top ofits stroke, andthe movement of the piston rods 14and 15 impart a rocking oroscillating motion to the beam24 anda consequent reciprocatoryi' movement ,to the pis-vv ton rods 28 and 29 which reciprocatory movement may beutilized by .mechanism,

' not herein shown in detail, to pump" water,

into and out of the cylinders 32 and 3.3.

- The pins in the opening and closing links 39 and '40,. intheir movement in one'direcv tion encounter the ends of the levers 45 and 46'which are then moving in an opposite di 1 rection thuscausing the valves 19 and 20fto be quickly and surely shifted from an open to a closed or from a closed to an open'posl tion, as the case may be, such shifting of the valves belng much more quickly accom plished by reason of the movement of thelower arms 45 and 46 than it could be accomplished if the pins 49, 50, 51 and 52 were caused to engage with fixed devices on the frame as mightbe one. 7

The operation of the device shown in Figs. 3 and 4, is similar to theoperation of the device shown in Figs; 1 .and 2, except that each of'the pistons 53 and 54 is pro vided with a'ftwo part valve 'instead'of a single valve, such two'part valves being pivotally mounted within the pistons 53jand 54.

and there adapted, I when closed, :torest against the valve stops 55, 56, and 57,'and each part of each of such'valves is connected shows the valve sections 58 and 59, closed in such manner that water impinging against such valve sections will move thepiston 53 upwardly until the'end of the link/l5 strikes against the pin to open such valve sections 58' and 59 at the "end-of the working stroke of the piston 53, theend of the'link 46striking against'the "pin 7 8 at the same instant v and closingthe valve sections'60 and 61 to of the beam 24'and the outer end of the lever i reverse'the direction ofmovement of the.va-"

rious parts.

My hydraulic motor isadapted to operate sure of the water in such pipes.

Obviously, numerous changes m-the form.

of the various details embodied in my hydraulic motor may be resorted to'without'departing from the spirit of my invention or sacrificing any of its advantages.

WVhat I claim is:

1. In a hydraulic motor of the class described, the combination with a frame, of two cylinders secured to said frame, a piston disposed to be movable in each of said cylinders, piston rods connected with said pistons, a walking beam pivotally secured to said frame, said walking beam being pivotally connected at each end with one of said piston rods,'valves pivotally disposed in each of said pistons, opening and closing links articulated with each of said valves and provided with limitstops, lever arms pivotally secured to said frame, and links connecting said leverarms with said walking beam whereby said lever arms may be caused to engage the limit stops of opening and closing links to open or close said valves.

- 2. In a hydraulic motor of the class described, the combination with a frame, of

its ends articulated with said piston rods and its medialipoint pivotally secured to said frame, lever arms fulcrumed on said frame,

links connecting said lever arms with said walking beam, valves pivotally mounted in said piston, links connected with said valves and adapted to be actuated by said lever arms to opensaid valves whensaid pistons 1 are at the end of their working stroke and to close said valves when said pistons are at the end of their idle stroke.
